Menu.
5. Press and hold down the BLANK key.

This will refresh the stored BLANK value; it can be refreshed only after a
completed analysis cycle with the analyzer in stand-by mode.
6. Reconnect the sample line to the fast-loop reservoir.
6.3
SLOPE (FACTOR) CALIBRATION
A manual factor (slope) calibration should be performed during the initial start-up, after reagent
replacement, and after any period of extended shut-down. The recommended and default setting
for automatic calibration is approximately once per week.
1. Login with the 1st level service password (1111).
2. Connect the CAL tube to the calibration standard.
3. Check that the calibration standard is the correct concentration.
a. From the PROGRAM Menu, select CALIBRATION.
b. The concentration of the standard is displayed in blue.
c. To change the standard concentration, press the displayed standard value.
d. Type the new concentration and select ENT.
4. From the RUN Menu, select EXTRA. The analyzer will perform a calibration cycle and
store the new calibration factor.
5. Perform an EXTRA Cycle two to three times with the calibration standard to ensure a
repeatable calibration factor.
6. To check the value of the calibration factor, from the PROGRAM Menu select
CALIBRATION to open the calibration menu window.
6.4
SINGLE ANALYSIS CYCLE
The analyzer can be set to run either in continuous analysis mode or single analysis mode.
Follow the steps below to perform a single analysis cycle.
NOTE:
When starting the analyzer for the first time or restarting it
from any period of shutdown, do not proceed to run an
analysis cycle until a calibration has been performed.
1. Connect the sample tubing to the fast-loop reservoir and turn on sample flow to the fast
loop reservoir.
2. Check that the sample fills the fast loop reservoir so that the float switch rises and sample
is being discharged from the overflow drain.
3. Perform an analysis cycle by pressing the RUN Menu and selecting CH 1.

The absorbance detected by the analyzer is used along with the blank and
calibration values to determine a concentration in ppb.
4. When the analyzer has finished the analysis cycle, the concentration reading will be
displayed on the main screen. The result can also be found in the data logger.
5. The analysis returns to standby mode and waits for another user command.
